I just finished buying a set of american racing long tube headers with catalytic converters w/ y-pipe that will be connected into my dB corsa catback exhaust system. I also bought a 87mm throttle body from Moe's Performance which should optimize the mopar CAI I have in there now. Then I just ordered and scheduled an appointment with the offroad shop that did my lift to have installed 4.56 gears with detroit truetracs in the front/rear too. Finally, I bought a set of 20x10 Moto Metal Chrome 951 wheels to replace my KMC XD Rockstars. I think once all of these are installed, in addition to the diablo trinity and getting a hemifever tune, mopar cai and corsa exhaust I have now, this truck will have to be pulling well over 450 h/p...thoughts??

 

You have too much money and should give me some.


And remember, PICTURES.

 

Money? Yes, I am blessed. But I also don't have much of a personal life because I work essentially everyday. Does anyone here think they could project what kind of h/p I will see once everything is done?

Once done, the following modifications will be done to the truck:

-Mopar CAI
-87mm Throttle Body
-American Racing Longtube Headers w/ y-pipe
-dB Corsa catback dual exhaust
-Diablo Trinity T-1000
-4.56 gear ratios

 

Considering the Hemi has 390 at the crank, I'd estimate something like 440 at the crank. Then figure in all your drivetrain losses.

 

How much does all that add up to? For about $4,000 you can supercharge your 5.7

 

Alright guys, I think I could your input. If you were me, where would you invest your money: longtube headers or a 4.56 gear swap? They both are going to cost me the identical price but I think it would be ill-advised to purchase both simultaneously. Your help would be big.

Also, are the JBA shorty headers not worth buying? Or do they provide noticeable gains in horsepower with a CAI, 87mm throttle body, and a catback exhaust system?

 

gears

 

+2 on gears.

 

Excellent - gears it is! I guess they already shipped the throttle body so I'll just plan on installing that. Should I expect any noticeable gains from that or what?

 

You likely won't see any gains unless you have some more serious mods that would require the mass movement of air into and out of the engine.
